ALLOC A.MPTUS. — STAUliOPODOCTONUS. 375 



basal half less siuuate and two especially piomiuent lateral lueta- 

 thoracic carinae. 



The type was captured by Thwaites in Ceylou in 1873. 

 A female was bred in the Calcutta Miiseuiu from the larva 

 of a moth, Trahala vishnu, found on a castor-oil tree in that 

 city ; it emerged from its host on 2Gth March, 1894. 



272. Allocamptus inflexus, sp. n. 



c? 2 . A large, pale testaceous species, the only black marks being 

 at the base of the front «ings behind the tegulse. Head narrow 

 behind eyes. TJwrux with the metathorax finely and not very 

 distinctly trans-striate, with the striae laterally all equally strong. 

 Sctdellum margined. Wings with a distinct glabrous area in first 

 cubital cell, the base of the radial nervure testaceous, strongly 

 bisinuate, and the costa and stigma testaceous. 



Length, 2 27 milliin. ; (S 17 millim.

Type 2 in the Oxford Museum. 



This species dift'ers from A. shmatus in its shorter and stouter 

 basal segment, more finely striate metathorax, distinct nervelet, 

 much shorter first discoidal cell, testaceous costa and stigma, with 

 the latter much broader and emitting the concolorous radius less 

 obliquely and more directly. It is extremely like A. nndidatus, 

 Grav., but I am able to distinguish it by the posteriorly very much 

 more narrowed head, the less basally sinuate and testaceous radial 

 nervure and the distinct nervelet, which is emitted from the 

 geniculate centre of the first cubital nervure, whereas in the latter 

 species it is geniculate, with no nervelet distinctly beyond the 

 centre ; the angle at which the stigma emits the radius and the 

 conformation of the basal segn)ent is the same in both. 



The male difi"ers from the female in nothing hut its much smaller 

 size and more slender conformation ; it closely resembles Benico- 

 spilus Jiavicajiu t.

Clypeus apically transverse : labrura prominent, apically roundl} 

 constricted and olten longer than halt the clypeus. Abdomen 

 strongly compressed and more than double the length of the head
